VEGETABLE-SLICFER.

SPECIFICATION forming part of Letters Patent N0. 557,914, dated April 7, 1896.

' Application filed September 3, 1895. Serial No. 561,372. (No model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES BRUCE STRU- BLE and CORNELIUS S. TURNER, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Vegetable-Slicers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to that class of vegetable-cutters which are serviceable for slicing potatoes or other vegetables into thin strips of angular form, in cross-section, suitable for the so-called Julienne potatoes, Julienne soups, 850.

Our present invention is in the nature of an improvement on the device disclosed in our former United States patent, No. 527,253, dated October 9, 1894, for a potato-slicer. In said prior patent the series of vetical knives therein employed were made of individual pieces, which were set into the Wooden bed and there secured by wedge-shaped pins or similar devices. It has been found extremely difficult, at commercially practicable prices,

to permanently secure these individual knives in their proper working positions with the above-noted arrangement. Cheap woods will shrink and the knives become loose, and the few kinds of wood which would hold the knives are too expensive.

Our present invention has for its object to provide a slicer which will be free from the above-noted limitations, and is especially directed to the cutting devices, with a view of increased efficiency, durability, and economy of cost.

To these ends our invention comprises the details of construction hereinafter described,

and defined in the claims.

The accompanying drawings illustrate our invention, wherein, like letters referring to like parts throughout the several-views- Figure 1 is a plan View showingone form of our improved slicer. Fig. 2 is a vertical longitudinal section of the same, taken on the line w 00 of Fig. 1. Fig. 3 is a plan view of one of the cutters removed, the cutter being shown as only partially finished; and Figs. 4

and 5 are respectively front and end elevations of said cutter. Fig. 6 is a plan showing another form of our slicer. Fig. 7 is a longitudinal vertical section taken on the line 00 m of Fig. 6. Fig. 8 is a bottomplan view of the pivoted knife-carrying section, and Fig. 9 is an end view of the same.

Referring to both forms of our slicer, a a (I represent the sectional body or bed portions thereof, which are secured between side marginal strips 1). Of these parts the section a a is fixed to said side strips 1), with the reduced portion a extended beyond the same and provided with a central hole or perforation a adapting said part a to serve as a handle and as a means of hanging up the slicer 011 a hook or nail; and the section a is pivoted to said side strips 12 by screw-bolts b,

or other suitable device, at the rear end of the slicer, and is secured in any desired angular adjustment with respect to the section a a by a suitable clamping device. Said clamping device, as shown, comprises a headed and screw-threaded draw-bolt a, working through said side strips 1), and an enlarged passage 0, in said section (1 and fitted with a washer c and thumb-nut 0 The bolt-passage or transverse hole a in the pivoted section a is of a size to permit the maximum adjustment required for the said section a The two sections a and a are separated by a transverse or diagonal clearance or delivery slot (1, through which the finished product is delivered from the slicing-knives. Thus far both of the illustrated forms of our slicer are alike, but the knives or cutters proper are somewhat different.

Referring now to Figs. 1, 2, 3, 4, and 5, f is a horizontal slicing-knife secured to the upper edge of the pivoted section a facing the slot d, by means of lag-screws f or in any other suitable way. Oooperatin g with this horizontal knife f at the opposing wall of said slot cl is a cutter g g, secured by means of lagscrews g or otherwise to the fixed bed-section a. This cutter g g is made of sheet-steel or other suitable sheet metal, so cut and shaped as to form the fiat or body portion 9 and the upturned cutter-sections or knives g. The

nal line transverse of the slicer-frame; or, in other words, the said blank is of rhomboid shape. The method of forming this cutter g g is, first, to cut in one edge of the blank plate or strip g a series of transverse oblique slits, as shown by the full lines y on the unfinished portion of the cutter in Fig. 3, and then to turn the angular portions y thereby formed in said plate upward on angular lines running from the opposite extremes of the ad jacent slits y, as shown by the dotted lines 3 in Fig. 3. By this operation the said angular portions 1 are transformed into the series of vertical knives g, standing at right angles to the body portion g of the plate and parallel with each other and the ends of said plate. When the cutter g g is placed in working position, the body portion g will be adjacent to the passage 61 and the knives will project upward from the edge thereof, as shown in Figs. 1 and 2. It should also be noted that the plate or strip 9 is countersunk into the bed-section a, so that its upper surface lies flush with the upper surface of said bed-sec tion a. The cutter g g when thus formed and set is ready for cooperation with the horizontal knife f, and it is obvious that the series of ver-. tical knives will cut potatoes or other vegetables in the vertical plane, while the horizontal knife f will cut the same in the horizontal plane, and the conjoint result will be strips of rectangular or cubical form in crosssection, suitable for Julienne potatoes, &c.

The cutter employed in the construction shown in Figs. 6, 7, 8, and 9 is made in substantially the same manner as the one just described, but is applied reverse side uppermost. In this construction, however, the plate or strip 7t, in addition to having the series of vertical knives has also the serrated edges, which are left on said strip 7c by the cutting and turning of the knives is, sharpened to form horizontal knives or cutting edges 70 In this latter construction the strip or plate 7t is secured by means of lag-screws 703 or otherwise to the forward edge of the pivoted bed-section a with the vertical knives 7c turned downward into the passage d in line with the rear edge of the fixed bed section a. In this construction and arrangement the one piece or cutter-plate 7.; It serves of itself to cut the vegetable into the cubical strips, and hence removes the necessity for the horizontal knife fused in the device illustrated in Figs. 1 to 5, inclusive.

. It will be noted that in the cutter illustrated in Figs. 1 to 5 it is the inner vertical edges of the upturned knives g that are sharpened, while in the cutter illustrated by Figs. 6 to 9 it is the outer vertical edges of the downturned knives 70, as well as the horizontal cutting edges 71: thereof, which are sharpened. The result on the potato or article being sliced will be the same as with the construction shown in Figs. 1 to 5. In both forms the series of vertical knives are formed integral with the horizontal or body portion of a common plate, which may be readily and securely made fast to the bed of the slicer. Hence the vertical knives are just as permanent as the horizontal knives. Moreover, the said cutters, in these forms, may be quickly and cheaply made by stamping the same from sheet-steel.

By actual experience we have demonstrated the efficiency of this invention. Details may of course be changed without departing from the spirit of our invention.

Vhat we claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In a slicer, a cutter having a flat or body portion and a series of cuttersections or knives integral therewith and at right angles thereto, formed from a single blank by slitting one margin of the blank and turning up the parts intervening between the slits on lines connecting the opposite extremes of adjacent slits, substantially as described.

2. In a slicer, a cutter having a flat or body portion and a series of cuttersections or knives integral therewith and at right angles thereto, made from a single blank by forming in one margin of the blank a series of transverse oblique slits and turning up the intervening angular portions between the slits on obliquelines-connecting the opposite extremities of adjacent slits, substantially as and for the purpose set forth.

3. In a slicer, a cutter, having a fiat or body portion and a series of cuttersections or knives integral therewith and at right angles thereto, made from a single metallic blank of rhomboid shape by forming in one side margin thereof a series of oblique transverse slits and turning up the intervening angular portions between the slits on oblique lines connectin g the opposite extremities of adjacent slits, whereby the upturned cutter-sections will be parallel with each other and the ends of the cutter-body, substantially as described.

4:. The method of forming cutters for slicers or other tools, which consists in stamping or cutting out from sheet metal a rhomboidal blank with a series of transverse oblique slits in one side margin thereof and then turning up the intervening angular portions between 'said slits on oblique lines connecting the opposite extremes of adjacent slits, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
